AUTOMATIC CAR-GATE.

QPECIFICATION forming part of Letters Patent N0. 760,536, dated May 24, 1904. Application filed June 4, 1903- Serial No. 160,058. (No model.)

To all whom it may concern.-

Be it known that I, I/VI LIAM N. HAcKnTT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Automatic Car-Grate, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to automatic gates for use on electric and other cars; and the object of my invention is to provide simple and effective means for closing one side of open cars in order to prevent passengers entering and leaving the car on that side.

A further object of my device is to secure means whereby the gates may be opened and closed automatically on either side of the car by turning over the seat-backs.

Broadly, my invention consists of a gate pivotally mounted on a pin and provided with a curved slot engaging a pin in the seatback in such manner that the gate is opened or closed by turning the seat-back.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a plan view of the cargate; Fig. 2, a view in perspective of a section of a car, showing two seats provided with the car-gate; Fig. 3 is a view of a cross-seetion of a car, showing three seats equipped with the gate and showing the movements of the gates in reversing the seat-back. Fig. 4 is a side elevation of a seat provided with double gates. Fig. 5 is a front elevation of the double gates, and Fig. 6 is a side elevation of the detail of the gate.

In the several views similar letters refer to similar parts. 1

In the drawings, A represents the gate, in which a is the blade, and a is the lixed end, pivoted on the pin a? and provided with a curved slot (0", the long sides of which are arcs struck from said pivotal center and the long axis of said slot being approximately a quarter of a circle and starting from the base of the blade a.

B is the car, having the seats 7), b and 5, provided with reversible backs I), If, and I)", the seat-backs being attached in the usual manner by the brackets b and pins I) to the side posts 1) of the ear and turning on the pin 1). The gate A is pivotally hung on the pin b between the seat-bracket Z2 and the sidepost I)", and the pin 1) on the seat-bracket b is so placed as to engage said curved slot a of the gate and to move the gate when the scat-back is turned.

In Fig. 3 is shown a section of a car containing three seats, the seat-backs being in three different and successive positions in order to showhow my gate may be openedor closed by turning the seat-back. On seat I) the gate is shown as open and in an upright position, the bladed being in alinement with the side posts 6" and retained by the catch 0, which may be of any suitable form. As thus shown, the side of the car is open to permit the entrance and exit of passengers. If it is desired to reverse the car and close the gates on that side, it may be done by simply turning the seat-backs. Seat 6 shows the seatback half turned, and the pin if on the side bracket of the seat-back has moved ninety degrees in the slot a and has come into.engagement with the upper end of the slot a, and as the seat-back is turned farther the pin 5" carries the gate through an arc of ninety degrees'until it reaches the position shown on seat 6, where the gate is closed and the blade a is horizontal. In this position the end of the blade (1 engages a catch a to prevent a seat the space between it and the rear dasher of the car. This leaves the space between the frontseat and the front dasher open, and in order to close this interval I provide an additional gate, arranged as shown in Figs. 4 and 5, which is also operated by turning the seat-back, but in an opposite direction to the first-described gate. To accomplish this result, I use the gate D, pivotally mounted between the gate A and side post 6" on the pin cl, which is set in the side post above the pin b and by means of the gears a and d on the gates A and D, respeetii ely, any movement of the gate A causes an opposite and equal motion of the gate D in such manner that when the gate A is closed the gate D is also closed, and by turning the seat-back both gates are raised into alinement with the side post of the car and out of operation. It is possible to use this construction on every other seat instead of mounting one gate on each seat; but.

the latter form is simpler.

If preferred, instead of the catches c and c the end of the blade of the gate may be provided with a pin, as shown in Fig. 6; which will engage the arms of the seat or the side post'and confine the movement of the gate within the desired limits.

My device may be used on both sides of a car, and by reversely mounting the gates it will be so arranged that the gates on one side' of the car are always closed, and by turning the seat-backs the closed gates are thereby automatically opened and the open gates closed.

By means of my device it becomes impossible for a passenger to open the gate without turning over completely theseat-back in front of him.

What I claim is 1. In an open car having reversible seats, an automatic car-gate consisting of a guard and a reversible seat-back, both mounted upon a single pivot in the side post of the car; said guard being provided with a curved slot in its pivoted end concentric with said pivot and said seat-back having in its side bracket a pin fixed and adapted to engage said curved slot in such a manner that when the seat-back is reversed the said guard is turned on said pivot through an arc of approximately ninety degrees.

2. In an open-sided car having seats with reversible backs, a reversible seat-back pivotally mounted upon the side posts of the car, and having in its side bracket a fixed pin, in combination with a guard pivotally mounted at one end upon the seat-back pivot; said pivoted end being provided with a curved slot having an are approximately of ninety degrees concentric with said pivot and so arranged in relation to said fixed pin that when the seatback is reversed the said fixed pin engages said curved slot and revolves the guard through an arc of ninety degrees.

3. In an open car having reversible seats, an automatic car-gate consisting of a guard pivotally mounted at one end upon the seat-back pivot in the side post of the car, said guard being provided in its pivoted end with a curved slot having an arc of approximately ninety degrees concentric with said pivot; and a reversible seat-back pivotally mounted on said side post and provided with a fixed pin on its side bracket; said curved slot and said fixed pin being so arranged in relation to each other that when the seat-back is turned through an arc of about one hundred and eighty degrees, the said guard is moved through an arc of about ninety degrees and locked.

4. An automatic car-gate in an open car having reversible seats, consisting of a guard pivotally mounted at its enlarged end upon the seat-back pivot in the side post of the car, said guard being provided with a curved slot concentric with said pivot; and a reversible seat-back pivotally mounted on said side post and provided with a fixed pin on its side bracket so placed as to engage said curved slot in the guard, all being so arranged and disposed that the turning of the said seat-back causes the said guard to revolve through an arc of ninety degrees.

5. An automatic car-gate in an open car, consisting of the guard A pivotally mounted at its enlarged end (0 upon the seat-back pivot b in the side post 6 of thecar, said guard being provided with the curved slot a concentric with the pivot 6 and a reversible seatback I) pivotally mounted on the pivot L on the side post 6 and provided with the fixed pin 5 on its side bracket If, so placed as to engage said curved slot a in the guard A, all being so arranged and disposed that the turning of said seat-back 6* causes the said guard to revolve through an arc of ninety degrees.

6. In an open car having reversible seats, an automatic car-gate consisting of a guard, and a reversible seat-back both mounted upon a single pivot in the side post of the car; said guard being provided with a curved slot in its pivotal end, concentric with said pivot, and said seat-back having in its side bracket a pin fixed and adapted to engage said curved slot in such a manner that when the seat-back is reversed the said guard is turned on said pivot through an arc of, approximately ninety degrees; a gear-wheel, fixed to said first guard; and a second guard, pivotally mounted upon said side post, and fixed to a second gear; said second gear meshing with said first gear; all designed to open or to close said guards simultaneously by reversing said seat.
